One of New York's wettest days in decades left the metropolitan area stunned and swamped Friday after heavy rainfall knocked out several subway and commuter rail lines, stranded drivers on highways, flooded basements and shuttered a terminal at LaGuardia Airport for hours.
Some 8.65 inches (21.97 centimeters) of rain had fallen at John F. Kennedy Airport by nightfall Friday, surpassing the record for any September day set during Hurricane Donna in 1960, the National Weather Service said.
Parts of Brooklyn saw more than 7.25 inches (18.41 centimeters), with at least one spot recording 2.5 inches (6 centimeters) in a single hour, according to weather and city officials.
More downpours were expected Saturday, The Associated Press reported.
The deluge came two years after the remnants of Hurricane Ida dumped record-breaking rain on the Northeast and killed at least 13 people in New York City, mostly in flooded basement apartments.
Gov. Kathy Hochul and Mayor Eric Adams declared states of emergency and urged people to stay put if possible. But schools were open, students went to class and many adults went to work, only to wonder how they would get home.
Virtually every subway line was at least partly suspended, rerouted or running with delays. Metro-North commuter rail service from Manhattan was suspended for much of the day but began resuming by evening. The Long Island Rail Road was snarled, 44 of the city's 3,500 buses became stranded and bus service was disrupted citywide, transit officials said.
